The present invention adopts the technical proposal that: the presentinvention provides a novel intelligent clean robot, which comprises amain body and drive wheels, cleaning brushes, a caster, induction lampassemblies, a suction port assembly, a storage box assembly, a fanassembly and a battery pack disposed in the main body and furthercomprises a front bumper disposed on the outside of the main body; thefront bumper is provided with hanging buckles and movably connected tothe main body through the hanging buckles; detection switches aredisposed on the outside of the front bumper; and infrared receivingdevices are disposed on the side of the main body.

As a further improvement of the present invention, the hanging bucklesare numerous and disposed on the inner upper side of the front bumper.

As a further improvement of the present invention, the detectionswitches are numerous and disposed on both sides of the front bumper.

As a further improvement of the present invention, the infraredreceiving devices are numerous and disposed on the machine. In theexample, one is disposed at a position close to a nameplate and theother two are symmetrically disposed at positions close to the cleaningbrushes.

The novel intelligent clean robot provided by the present invention hasthe advantages that: in the novel intelligent clean robot provided bythe present invention, the friction between the front bumper and themain body is reduced so that every position in collision with the frontbumper can be sensitively triggered; and the height of the entiremachine is reduced so that the machine can work at cleaning areas withlower height limit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Further description will be given below to the present invention withreference to the accompanying drawings and the preferred embodiments.

Reference numerals in the accompanying drawings: 1. main body; 2. drivewheel; 3. cleaning brush; 4. caster; 5. induction lamp assembly; 6.suction port assembly; 7. storage box assembly; 8. fan assembly; 9.battery pack; 10. front bumper; 11. hanging buckle; 12. detectionswitch; 13. infrared receiving device.

As illustrated in FIGS. 1 to 7, the present invention provides a novelintelligent clean robot, which comprises a main body 1 and drive wheels2 configured to drive the main body to move on the ground, cleaningbrushes 3 with cleaning function, a caster 4 with guide function,induction lamp assemblies 5 with the functions of preventing falls andreceiving signals, a suction port assembly 6 disposed on the lower partof the main body and used for vacuum cleaning, a storage box assembly 7configured to store garbage and dust, a fan assembly 8 with the airexhaust function, and a battery pack 9 configured to supply energy forthe machine, disposed in the main body. The novel intelligent cleanrobot provided by the present invention further comprises a front bumper10 disposed on the outside of the main body 1. The front bumper 10 isprovided with hanging buckles 11 and movably connected to the main bodythrough the hanging buckles 11. Detection switches 12 are disposed onthe outside of the front bumper 10. Infrared receiving devices 13 aredisposed on the side of the main body 1. The front bumper 10 isconfigured to change direction when sensing front obstacles or collidingobjects.

As illustrated in FIGS. 6 and 7, the hanging buckles 11 are disposed onthe machine (in the example, four hanging buckles 11 made frompolyformaldehyde (POM) materials are symmetrically disposed on the innerupper side of the front bumper); and the front bumper 10 is movablyconnected to the main body through the hanging buckles 11 so that thefront bumper 10 cannot be disengaged from the main body. When collidingwith an obstacle, the front bumper 10 can move within the range definedby the hanging buckles 11 and trigger and collide with the detectionswitch, so that the friction between the main body and the front bumper10 can be reduced.

As illustrated in FIG. 5, the detection switches 12 are numerous (fourin the embodiment). In the example, the detection switches 12 aresymmetrically disposed on both sides of the front bumper 10 to ensurethat every position in collision with the front bumper 10 can besensitively triggered. When the front bumper 10 collides with anobstacle, the collision position moves back and the detection switch atthe collision position is triggered to drive the wheelset to changedirection and keep away from the obstacle.

As illustrated in FIG. 4, the infrared receiving devices 13 are numerous(three in the embodiment). In the example, one is disposed at a positionclose to a nameplate and the other two are symmetrically disposed atpositions close to the cleaning brushes. When the front bumper 10collides with an obstacle, the collision position moves back and thedetection switch 12 at the collision position is triggered to drive thewheelset to change direction and keep away from the obstacle. Thefunction of the infrared receiving devices on the top is replaced andthe height of the entire machine is reduced so that the machine can workat cleaning areas with lower height limit.

The working principle of the machine is as follows:

1. When a power switch is pressed, the battery of the machine isswitched on. Under the control of an electronic control part, a fan, thecleaning brushes, a floor brush and the wheelset start to run.Meanwhile, sensors (for collision sensing and ground clearanceinduction) start to work, and the electronic control part controls themachine to make corresponding actions according to sensor signals.

2. When the built-in infrared detection switches on the front bumpersense the front obstacle, the wheelset and the caster change themovement direction.

3. When the induction lamps detect that the front is high up, thedirection will be changed to prevent falls.

4. In the vacuum suction mode: when the machine starts to work, a sidebrush motor and a fan motor are energized; the side brush motor drives aleft side brush and a right side brush to rotate to clean garbage in thevicinity of the machine to the vicinity of a suction port; under thedrive of the fan motor, the fan rotates at high speed, so that completehigh-speed air flow is produced in an air duct formed by a nozzle, adust chamber, a coarse filter screen, a coarse filter screen holder, adust chamber upper cover, a fine filter screen, a fine filter screenholder, an upper cover, a motor upper cover, a motor lower cover, alower cover and a battery cover; the high-speed air flow results inspecific pressure difference between the atmospheric pressure in theventilation system and the ambient atmospheric pressure, so thatspecific suction is produced at the suction port; in the travellingprocess of the machine, the floor brush mounted at the bottom of thelower cover is configured to clean the floor and collect the garbage onthe ground to an air inlet of the nozzle; with the accumulation of thegarbage, the cross section of the air duct between the air inlet of thenozzle and the external environment is smaller and smaller, and thesuction at the air inlet of the nozzle is gradually increased; and thecollected garbage is sucked into the entire ventilation system andeventually stored in the dust storage box.

5. When the dust runs through the nozzle and enters an inner space ofthe dust storage box, the dust is blocked by the coarse filter screen;large dust particles are blocked to the inside of the dust storage box,and relatively small garbage continuously moves ahead along the airdust; when running through the fine filter screen, relatively smallgarbage particles are blocked by the fine filter screen and also blockedto the inside of the dust storage box; and the remaining extremely smallparticles continuously move ahead along the ventilation system and aredischarged into specific areas on the outside of the machine throughspecific holes on the upper cover under the high-speed drive of fanblades. The air flow is recycled through an exposed motor housing duringthe high-speed movement, and the heating motor is sufficiently cooled.

The foregoing is further detailed description given to the presentinvention with reference to the preferred embodiments and not intendedto limit the preferred embodiments of the present invention. A pluralityof simple deductions or replacements may also be made by those skilledin the art without departing from the concept of the present inventionand should all fall within the scope of protection of the presentinvention.
